In a essay,what are some of the tyrannies that human beings inflict on animals according to Old Major speech in chapter one?

I can't write an essay for you but here is a quote from Old Major's speech:

"Now, comrades, what is the nature of this life of ours? Let us face it:
our lives are miserable, laborious, and short. We are born, we are given
just so much food as will keep the breath in our bodies, and those of us
who are capable of it are forced to work to the last atom of our strength;
and the very instant that our usefulness has come to an end we are
slaughtered with hideous cruelty. No animal in England knows the meaning
of happiness or leisure after he is a year old. No animal in England is
free. The life of an animal is misery and slavery: that is the plain truth."
